Jonathan Aguero 👋

I’m a Senior Product Engineer focused on building intelligent, scalable software systems — from zero to production and beyond. I specialize in designing and developing end-to-end digital products, combining frontend excellence (React, Next.js), strong backend engineering, cloud-native architectures, and AI-powered solutions to create real business impact. My work sits at the intersection of product thinking, system design, and applied AI. I enjoy owning the full lifecycle: from early technical decisions and architecture design to development, deployment, and scaling on AWS. Core strengths: Building modern user experiences with React & Next.js Designing scalable backend systems (Node.js, NestJS, PostgreSQL, MongoDB) Event-driven and distributed architectures (SNS, SQS, serverless) Cloud-native development on AWS (Lambda, DynamoDB, CDK, Bedrock) Creating AI-powered applications using LLMs, RAG architectures, and intelligent agents Current focus: Generative AI & Large Language Models (LLMs) RAG architectures & Knowledge Bases on AWS AI coding assistants & agentic workflows Multi-agent systems and orchestration frameworks What truly drives me: I love crafting amazing user experiences from the frontend, while staying deeply technical under the hood. I consider myself a highly technical engineer, but 100% customer-oriented — obsessed with usability, clarity, performance, and building products people genuinely enjoy using. I’m particularly interested in building AI-first products, internal tools, and automation platforms that solve real operational and business problems.
